Certain non-trivial amount of work is need to be put into "parallel" fsck then.

I have idea of a "hack" that might work, though ;)
fsck -a may not close the device until it gets mounted (or some timeout passed).
Then mounting will get bitmaps out of the cache or at least I hope so.
Need to do some experiments.

Bye,
